so my 89 hatch has a check engine light turns on at about 1600rpms while in a forward gear and turns off after and will come back on at about 1800rpms
if i get on it, it will stay on until i turn off and restart my car...tried to get codes but theres no sti (self-test input) wire which is the lonely wire next to the eec4 connector
car seems to be running rich from what i can smell
any ideas??

if possible can anybody supply me with a A9L ecu wiring diagram??
